PIPING-GUIDE FOR SEWING- MACHINES.

SPECIFICATION forming part of Letters Patent No. 250,872, dated December 13, 1881.

Application filed August 22, 1881.

To all whom it may concern Be it known that I, SAMUEL N. BATES, of East Weymouth, of the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Piping-Guides for Sewing-Machines; andI do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a side elevation, and Fig.2 a front view, of a sewing-machine provided with my invention. Fig. 3 is a top view of the pipingguide and its abutment, the said figure showing their relative positions to the, needle and presser. Fig.4c is a vertical section of the pipin g-guide, needle, presser, and feeder. Figs.5 and Gare hereinafter referred to and explained.

In carrying out my invention Ihave combined with the sewing-machine a piping-guide movable vertically with the feeder, the latter being supposed to have mechanism for imparting to it lateral and upward and downward movements necessary to cause it to intermittently feed along a piece of work or material to be sewed, in order for the needle and shuttle to perform their duties of producing stitches or sewing.

I am aware that a rigid guide for a binding is not a new addition to a sewing-machine, the office of such guide being to properly direct the binding while being connected with the work by being sewed thereto. It has been found difficult, if not impossible, to employ with the feeder a rigid and stationary guide for supporting piping and guiding it to the needle, because the feeder in rising upward would force the piping out of place in the guide and work. It will thus be seen that to prevent this the guide should be movable vertically with the feeder. drawings is an elastic one, or, in other words, it has the qualities of a spring, and moves vertically with the work and the piping as they are pressed upward toward the presser by the feeder.

With myimprovement the guide can be used for introducing the piping in very acute angular spaces in work and about the vertices of such spaces, scalloped work, with piping laid in the scalloping, being easily sewed.

Although I employ an elastic piping-guide, I do not confine my invention to such, as it is The guide represented in the aforesaid.

(No model.)

one form or construction by which I am enabled to carry out such invention, the main principle of the improvement being a pipingguide vertically mo able with the feeder.

In the drawings, A denotes the sewing-machine, which may be supposed to have a needle, shuttle,feeder, and presser, with mechanism for the proper operations or workings of each, the needle being represented at a, the presser at b, feeder at 0, shuttle-race at d, and the shuttle at e.

To the work-supporting table or plate f of the machine the piping-guide B is fixed by means ofa clamp-screw, 9, going down through a slot, h, in the guide. A top view of such piping-guide is given in Fig. 5, and a side view of it in Fig. 6, it being a metallic tapering spring, having a groove, 0, in its front end to receive the piping. It is placed immediately aside of the needle and presser, in manner as represented, and rests against a stationary abutment, 0, formed as shown, and fixed to the platefby aclamp-screw,g, goingdown through a slot, h, in the shank of the abutment. The said abutment serves not only to support the guide against the lateral pressure exerted on it by the work, but admits of it moving upward and downward with the work and the feeder.

The piping consists, usually, of a strip of leather folded 'along its longitudinal medial line and scalloped at its edges, in order that it may be readily bent to conform to the shape of the contiguous edges of the work within which it is to be inserted. It is generally employed to finish the upper edges of a shoe or that of the leg of a boot.

The feeder c is attached to and projects upward from a slide-bar, h, provided with a retracting-sprin g, 6, arranged obliquely to it, as shown. A lever, 70, pivoted to the slide-bar h, works against a fulcrum, l, and is moved by a cam, m. The slide-bar, at its lower end, rests against another cam, a. By these cams, while in revolution, and by the spring, the up-anddown movements and advance and retreat of the feeder are effected, as in most sewing-machines, the said mechanism for operating the feeder being such as is in common use and well-known to persons skilled in the use of such machines, especially whatis termed theHowe machine.

With a piping-guide thepiping is guided by a groove only, it not being supported or held l ing-machine, a piping-guide grooved in its in place all around it, as acord is in a cordingguide, or a welt is in a welt-guide, there being with either the cord-guide or the welt-guide no liability or danger of the cord or welt being forced out of place, particularly out of the guide, by the feeder in rising upward, as occurs with a rigid piping-guide grooved on its frontendorthatnextthe needle. Consequently my invention overcomes a difficulty not incident to a welt-guide, particularly such as is described in the United States Patent No. 42,810, or a cording-guide, as described in the United States Patent No. 39,336, but only to a piping-guide having an open guide-groove, such as is shown in Fig. 6.

I claim 1. In combination with the feeder of a sewfront end, as described, and so applied as to be movable vertically with such feeder, as and for the purpose substantially as specified.

2. The combination of the elastic pipingguide B, grooved as explained, and its abutment 0, as described, with the feeder c and work-supporting plate f of a sewing-machine.

3. The piping-guide, grooved as explained, and the abutment provided with slots arranged in them, as set forth, to admit of the proper adjustment of them relatively to each other and the needle, as the size of the piping and its projection from the Work may require.
